The Preparation
Combine heavy cream and sugar in a saucepan.
Heat over medium, stirring, until it reaches just below a boil (a simmer).
Remove from heat.
Stir in lemon zest and lemon juice. The acid will thicken the cream.
Let cool to room temperature (about 30 minutes on the counter).
Pour into ramekins or small serving dishes.
Refrigerate for at least 2 hours until set.
Serve topped with fresh berries.
